Is there someone here who could help me golf a Pyth program?

@ETHproductions @isaacg

feersum

Is there any python module to add a ? : style ternary operator?

quartata

@feersum I thought Python had this.

Calvin's Hobbies

@feersum There is inline A if B else C

quartata

Ah right. That's how you do it

I haven't used Python is so long

feersum

@Calvin'sHobbies Of course. I mean a module to add a non-atrocious version of the ternary.

Like cond ? thing1 : thing2

Doorknob

3:55 AM

Rust's is if (cond) { thing1 } else { thing2 } which is pretty nonatrocious. :P

feersum

@Doorknob The braces are required?

I have no clue how to even start golfing this :/

Doorknob

@feersum yes

feersum

If the curly braces are needed, I'd say that qualifies as atrocious.

Doorknob

There's no such thing as if (foo) bar; in Rust.

quartata

3:57 AM

@Doorknob I thought you had to use match

I legitimately didn't know Rust had if

phase

if cond then a else b inline ternary in CoffeeScript

feersum

More atrocious than Python's even.

Doorknob

@quartata ...

@feersum Why? I mean, for golfing, sure, but...

quartata

Uh

That was awkward. (again)

What I meant to do was

A: When is Thanksgiving?

Objective C, 1470 bytes I don't code good but here objective c solution. #import <Foundation/Foundation.h> int dayForChar(char ch, int year) { int ym = year%28; switch(ch) { case 'k': if (ym == 0 || ym == 6 || ym == 17 || ym == 23) return 24; ...

Not golfed mods nuke pls

feersum

@Doorknob To write something like x = a ? b : c you would apparently need to have all those braces on one line, or use up several lines, which are both ugly.

Doorknob

3:59 AM

@feersum it's not ugly

feersum

@Doorknob Which one?

Doorknob

let x = if a { b } else { c };

feersum

The if parens are optional?

Doorknob

yes

feersum

That's even worse :P

Doorknob

4:00 AM

Actually they shouldn't be there

I put them by mistake because my Rust is rusty

@Doorknob No. But I am implying that there's a limited number of fixed length hashes, and no good reason to seed them with more bits than could possibly make a difference. And even if you did, it takes longer to hash a longer string.

@El'endiaStarman D:

El'endia Starman

Awfully nice of you, @Doorknob. Giving your life so another may live... :P

quintopia

@phase why is it pick 1

Doorknob

@phase because I don't know O

2

that should be an option -_-

quintopia

4:22 AM

@phase and if it's gonna be pick 1, why is there no all of the above

:P

phase

@quintopia "other"?

El'endia Starman

That's what I'd pick. "I don't know O."

quintopia

other counts as "none of the above"

El'endia Starman

As it stands, I did pick "other".

quintopia

@phase the real answer is that it has yet to prove itself as a contender for an "excellent golfing language"

@phase write more winning answers in it

phase

4:23 AM

@quintopia Yeah, there's still a lot to be added until it can compete with CJam or Pyth.

El'endia Starman

Oooh! The strawpoll is at 2/2! Doorknob might have a chance!

Doorknob

:D

quintopia

are there any cell-based golfing languages?

(3:2 against doorknob)

El'endia Starman

@quintopia I'd offer Minkolang but I'm pretty sure you're thinking of a different kind of cell. :P

Doorknob

nuuuu

phase

4:26 AM

@quintopia As in BF cells?

El'endia Starman

4 to 2 against Doorknob now!

quintopia

@phase yes

phase

@quintopia Well, there's BF, and every BF clone.

quintopia

basically "memory is one giant array"

@phase obvi not golfing languages

phase

I think an actual golfing language out of it would be quite verbose

El'endia Starman

4:28 AM

Not necessarily.

What makes golfing languages golfy is that they have commands that do a lot of stuff.

quintopia

@phase despite the fact that this is how RAM works?

even stack-based languages use the "one giant array model" under the hood

El'endia Starman

4:3 against Doorknob!

Doorknob

eeeek

feersum is more fearsome than me!

That's my proof :P

El'endia Starman

Anyway, anyone want to help me test my ideas for my next language?

quintopia

total scumtell

El'endia Starman

4:31 AM

As in, toss out simple programming exercises and I'll "solve" them.

quintopia

@El'endiaStarman what sort of language

phase

@quintopia That kind of memory model isn't easy to manipulate. Stack based languages are easy to manipulate because of popping and pushing, while managing a bunch of memory cells takes moving to that required cell, and then doing the manipulation you want.

quintopia

@phase that's a lot of assumptions about how memory is accessed

@El'endiaStarman have you already solved "output third largest in list"?

El'endia Starman

@quintopia Mathematica-level in terms of built-ins, uses tokenization like TI-BASIC (so something like \fold( would only be 1 or 2 bytes), and possibly uses stuff like APL's trains or other unique language features. If you have two functions/lambdas and multiply them, you get another function/lambda that will pass arguments to both functions and multiply them. That sort of thing.

I haven't started writing an interpreter or anything because I'm still thinking about its structure and language.

quintopia

What is fold again

phase

4:35 AM

@quintopia 1 2 3 /+ => 1+2+3

El'endia Starman

@quintopia Perhaps something like \fromRight(L,3

I think reduce is a synonym.

quintopia

So... Basically reduce?

Okay

El'endia Starman

yeah

Maybe I'd write it as \reduce(. Doesn't really matter.

quintopia

Sounds largely functional paradigm

El'endia Starman

The point is that it's 1 byte internally.

Yeah, maybe.

quintopia

4:37 AM

And golfy

El'endia Starman

Very golfy.

If I pull this off, it should beat Pyth.

quintopia

Can't wait to see that

El'endia Starman

That'd be cool, yeah.

But I also want to make it more than just an esolang. Like, it would be awesome if I started using it for purposes outside of PPCG.

quintopia

I'd like to see a Huffman coded language, where token lengths are measured in bits

El'endia Starman

I've thought about that a bit.

Like assigning a few common instructions to half bytes.

The issue is that the one-byte space is cut severely.

quintopia

4:41 AM

Huffman coding assigns bit sequences optimally given a sufficiently large body to sample the distribution

El'endia Starman

Yes, but how do you get that "sufficiently large body"? That's the problem.

Thomas Kwa

@quintopia There are many common pairs of characters

quintopia

You'd design the language first, use it for a long time, and then assign bits to tokens

Thomas Kwa

Taking them into account can get a little better than Huffman

I don't know Pyth well enough to know its idioms

El'endia Starman

You could analyze the specific instructions used in answers to PPCG, but the best in terms of distinct "ideas" might not be the golfiest, so there's a bit of a problem there.

quintopia

4:43 AM

@ThomasKwa then we let those common pairs be tokens

El'endia Starman

Oh, I got the "third largest item in a list" one wrong. It'd be more like \fromRight(\sort(L)3 for a total of 5 bytes.

I'm planning on writing a pretty complex parser so you don't need commas everywhere if it's unambiguous.

Thomas Kwa

@El'endiaStarman Be like Pyth and get rid of that close-paren

quintopia

How about "sort the tokens in my own listing"?

Thomas Kwa

I think making most operators vectorize on lists when they don't have other special meanings would help greatly

El'endia Starman

@ThomasKwa At this point, I don't think I really want to restrict variable names to one character.

I probably could do \fromRight(\sort(L3 for 4 bytes.

If there's no variable named L3.

Thomas Kwa

4:47 AM

Also trains would be very golfy

quintopia

@El'endiaStarman how many characters do you want in identifiers, and from which alphabet?

El'endia Starman

Or, y'know, \nLargest(L3 for 3 bytes.

Thomas Kwa

@El'endiaStarman That could actually be good

El'endia Starman

@quintopia I'd like to have a \name( function for assignment to variables. I'm considering making all commands start with `\` so you can use alphabetical characters without quotes.

Thomas Kwa

Pyth has a function where giving 'num,seq' as arguments does largest, but 'seq,num' does smallest, or something like that

El'endia Starman

4:49 AM

'course, \nLargest(L3 would only be 3 bytes if \nLargest( was 1 byte. I think it'd be more likely to be 2 bytes.

I want to not only have math, string, list, and function operations, but also graphics, file, internet, images, that sort of thing.

quintopia

Because you could just say "all pairs of lowercase letters are tokens, as long as no more than x different ones appear, each of which is assigned a byte code at compile time"

El'endia Starman

I figure that a lot of math functions will be 2 bytes. One byte to say "this is a math function" and one byte for which function. That'd give me 256 2-byte math functions. o_o

quintopia

Or really... You could tokenizing arbitrary identifiers at compile time

El'endia Starman

The golfiest solutions would tend not to have identifiers. Like, look at how rarely Pyth and CJam use variables.

(Though when they are used, they're very useful.)

quintopia

Not rarely in Pyth. Usually maps and stuff. Require variables.

El'endia Starman

4:53 AM

Well, okay. I've rarely noticed.

quintopia

But it hardly makes sense to talk about id3ntifiers there, since they did exactly what I'm talking about: predefined variables to be drawn from a particular set of byte codes

El'endia Starman

Uh-huh.

quintopia

It's just you could give those predefined bytes arbitrary names

El'endia Starman

Remember that I'm looking to make this language even more general-purpose.

Like, that I could write a complex project in.

quintopia

Sure. Hence suggesting allowing arbitrary names

El'endia Starman

4:55 AM

I read this article a couple days ago and I've been mulling over it since.

Like, how awesome would it be to have a \balancedBinaryTree( function that takes a list and optional function and ~~automatically~~ automagically does all the data structure work for you?

feersum

I think that article misses an important aspect of power in practice.

You need to be able to code close to the machine when it is necessary.
